Every Playboy Centerfold Combined

Have you ever wondered what every playboy centerfold would look like if it they were all put into one image? Chicago based Photographer, Jason Salavon created a series of portraits that combined every centerfold from the 1960s to the 1990s. While you can't see explicit details of each centerfold, you can see a silhouette figure that mimics that of foggy glass. This process, called amalgamation, was done with a program called ImageMagick.

I'm not sure I understand the point of this, or what the end products are supposed to demonstrate. They're too indistinct to draw any conclusions about the 'style of portraiture' as he describes on his website. Can anybody enlighten me?
